Bremdal Duration: 02/2014 – 02/2016 Location: Aalborg University, Denmark University of Zagreb, Croatia Narvik University, Norway Website: www.flexchev.com Contact: Bernt A. Bremdal, bernt@xalience.com Project setting • Internation project with 3 main participating parties (Aalborg University, University of Zagreb and Narvik University): • Focus on 6 areas of research: • Integration of energy storage systemin distribution grids as a vital part of smart charging station (CS) • Finding optimal storage technology and capacity • Control designt of charging stations to allow wide usage of electric vehicles • Mitigating the impact on power system and providing reserve to the system operator • Assembly of reduced scale experimental test benchto verfy the simulatanious operation of • Coordination concept between the proposed flexible electric vehicle charging infrastructure Project summary Hybrid electric vehicles chargers are expected to play a significant role in the total consumption of developed countries across the world. Besides, there is a global tendency to make power systems independent of fossil fuels by additional increase in the shares of renewable energy resources. Both of these effects tend to push the future power systems more and more towards the boundaries of safe operation. Today’s commercially available HEV chargers are not flexible and present significant disturbance sources for the grid. On the other hand, flexible chargers proposed in academic literature introduce several drawbacks mostly concerned with compromising the comfort level of vehicle owners and rapid degradation of HEV’s batteries. Therefore, preservation of power systems secure operation will require new interventions to increase the flexibility of HEV chargers in a cost-effective way. Proposed project is focused on theoretical development and experimental verification of a new generation of fast HEV charging stations (CSs). Its principal functionality is to use dedicated energy storage system within the station to compensate the adverse effects caused by charging, as seen from the grid. Flexible fast CS will be an essential part of the future intelligent power systems as projected by the smart grid concept. There is also the question involving the relationship between the cost and benefit of an applicationof different energy storage technologies. Therefore ageing models and assesment of various technologies baesd on rain-flow approach will be done. Based on the areas of application and the findings across the applications, open questions concerning further development of energy storage technologies, control methods for charging stations infrastructure and development of a business model will be analysed. The international consortium brings together leading research institutions and industrial companies from native countries of involved partners. Final experimental tests for developed control strategies will be carried after the results from the partners are consolidated into a system oriented integral platform. Verifications will be done in the intelligentMicroGrid laboratory, a world-class experimental facility at Aalborg University. Vision The vision of the Flexible Electric Vehicle Charging Infrastructure project is the development of an integrated concept of smart charging stations. In this project, a new concept for flexible electric vehicles charging stations will be developed using emerging technologies and control methods deployed in distributed generation systems and microgrids. To that end, a novel distributed coordination strategy between the grid and dedicated energy storage systems converters will be implemented, providing seamless expandability and robustness of the system. Theoretical analysis of grid performance indicators in the case of high HEV penetration will be conducted. Dynamic system model of fast hybrid electric vehicles charging station based on different energy storage systems technologies will be developed. Real time simulation study and assessment of operation will be conducted on a laboratory experimental rig on reduced scale model located in Denmark, Aalborg university. Finally, conceptualization of ancillary management service to balance charging needs with grid/market demands will be done. KEY QUESTION KEYWORD It will explore the possibility of using a dedicated energy storage system (ESS) within the charging station (SC) to alleviate grid and market conditions but not compromise the electric vehicles’s (EV) battery charging algorithms or change daily routine of the EV owner.
